You should avoid LED lighting 10 things

Have you considered upgrading lighting? The following are the 10 most people often make mistakes, read carefully, can let you avoid detours.

1 buy light distribution is not consistent

This is probably the most common problem upgrade. LED lights and lamps tend to have more directional output. So, for example, if you use LED to replace halogen lamp, spill light will be much less. This spill light is actually useful, for example, to illuminate the hotel corridor walls. Similarly, if you replace the fluorescent lamps with LED, 1/3 of the walls in the eye shadow.

The best way to avoid: first buy samples.

2 buy the light too dark or too bright

If you are considering using LED to replace fluorescent lamp, not only matches the light output (measured in lumens or LM). The LED lamp is directional, light output of the same, may get more light from LED. But please note that the light output data table may be exaggerated, and the light distribution of different can make the room look bleak.

The best way to avoid: buy a reputable brand, in the existing lamps to check the sample or samples in the laboratory.

3 buy the lamp is too cold"

Color is the color of light source said the scale, the unit is K (Kelvin). 2700K general incandescent lamp, halogen lamp for 3200K. If you use 5000K LED instead of these lamps, the space will seem to feel very cold.

The best way to avoid: check and sample purchase specifications.

4 buy the color looks very dull light

The color index is a measure of the light to show the ability of color, namely CRI. Normally, you need a CRI of 80 or 90 lamps. A weakness of the LED lamp is R9 (red) value, because it is not included in the CRI survey. Ensure that the R9 is more than 80, otherwise, it looked like a dull red.

The best way to avoid the CRI value to the supplier.

5 lights and dimmer is not compatible

LED realize smoothly in incandescent lamps or halogen lamps for the dimmer light cannot be raised. In fact, at a low level, often flashing and flashing. This is because the incandescent lamp and halogen lamp as a light regulator provides a standard resistor load, and the LED circuit the load does not match, sometimes two sets of electronic equipment are vying for dominance, leading to component failure.

The best way to avoid the need to use the LED test: dimmer, or add a "virtual load", such as an incandescent lamp.

6 do not check the supplier

Over the past few years, a large number of new LED lighting suppliers to enter the market. Therefore, it is necessary to carry out verification. For example: they are a reputable brand? They are a member of the guild? The company in the industry how long? Whether they are in testing institutions have the credibility of the product? Whether they are in the local office?

The best way to avoid: check in online, then ask around.

7 there is no decent warranty

The supplier will give you warranty? Is the nearest warranty? The warranty period is longer than the supplier in the industry? Look at the details of warranty details. Sometimes, you have 90 days to separate online registration to activate your warranty card.

The best way to avoid: choose a reputable manufacturer, read carefully the terms of the warranty.

8 buy non durable lamps

At present in the LED industry, it is generally agreed that LED rating life is the flux attenuation to the initial value of 70% when the working time is L70. For example, you may see the rated life of 50000 hours L70. In addition, the brochure often Monogram optimistic ratings. But also have a "premature failure" phenomenon.

The best way to avoid: ask them to suppliers based on the L70 rating of which test.

9 there is no long-term consideration

For example, a lamp for you within 18 months on the bad. You call the supplier, to another, he or she said: "we do not produce this model, we can provide the latest". It is worth noting that the latest and now you may look different on the ceiling lamps. What is worse, the producer does not exist.

The best way to avoid: if the lighting is the key word, can buy additional lamps as a backup.

10 the light was too bright

When using LED, with particular attention to the problem of glare, especially in the office. Usually, the LED panel will be delivered to all the light diffusing surface of the lamp, so too much light. Evaluation of glare have a good evaluation method, that is UGR (UGR), values should be below 19.

The best way to avoid: brightness calculation, calculation of UGR; or request the supplier to provide the installation example based on UGR rating. (compiled: LED James)
